METALLIC PACKINGI-RING.

SPECIFICATION forming part of Letters Patent No. 395,217, dated December25, 1888.

Application filed February 11, 1888. Serial No. 263,725. (No model.)

To aZZ whom it may concern:

Beit known that I, JOHN B. DEEDS, a citi' zen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Metallic Packing-Rings; and I do hereby declare the following to be a full, clear, andexact description of the inveution, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in valveand piston-rod packing-rings; and it consists, substantially, in suchfeatures of construction thereof as will hereinafter be moreparticularly described.

The object of the invention is to supply a packing-ring of suchconstruction as that no disconnection of the rod is required for itsinsertion in the stuffing -boX; also, to prevent rusting and wearing ofthe rod, as well as to prevent leakage, all as will more fullyhereinafter appear when taken in connection with the accompanyingdrawings, wherein Figure 1 is a longitudinal sectional view of astuffing-box and gland, together with a valve or piston-rod inelevation, having thereon a packing-ring embodying my invention. Fig. 2is a diametric section of the ring, showing its form of construction.Fig. 3 is a view in perspective of the two parts or segments of whichthe ring is constructed.

According to my invention I form the packing ring or sleeve of two partslongitudinally, and in one partl provide openings or recesses adapted toreceive small corresponding projecting portions or pins on the otherpart. ()ne end of the ring is formed -shaped,while the outer sidethereof is straight, so as to furnish surface enough to insure its beingkept straight within the box.

Reference being had to the several parts by the letters marked thereon,A represents a stuffing-box, B its gland, and C the valve or piston-rod,all. of which are of well-known construction or form, and the workingsof which are understood.

D represents as a whole a packing-ring of my present invention, which,as shown, is formed of the two segments or portions having the holes oropenings 1 1, while the other portion is formed or provided with corresponding lugs or pins, 2 2, adapted to enter such openings, and when thetwo portions are united in this way it will be seen that in use theywill be kept intact and be prevented from slipping apart or away fromeach other. The outer side of the ring is formed straight, as shown atso as to furnish sufficient bearing-surface to maintain the samestraight within the stuffing-box. The bore or interior of the ring isformed also with a small straight flange, 0, which adapts a betterhearing or fitting of the said ring to the rod. One end of the ring ispointed or -shaped all around, as seen at d, from which construction thepacking surrounding the ring will in use be forced to both the rod andthe walls of the stuffingbox, as in the manner of being spread apart bya Wedge. The other end of the ring is cut away or beveled, as seen at e,and which construction also serves to maintain the surrounding packingagainst the rod.

Filling the interior of the stuffing-boX around the ring D and the rodis a packing compound, say, of hemp, flax, or other equivalent material.In practice, however, I prefer to employ the compound set forth in anapplication filed of even date herewith, Serial No. 263,674; but I ofcourse am not limited in this case to the use of such material, since Ihave found many well-known kinds to answer.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a valve-rod packing, the metallic ring D, constituted of two partshaving corresponding openings and pins by which they are held together,one end of said ring being pointed and the other end cut away orbeveled,while the outer and inner sides thereof are formed with thestraight bearing-surfaces b and c, in combination with a packingcompound of textile material, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. DEEDS.
